'nssrm on mnn nunn,"GERMANY The invention: relates to railway cross ties v anda-more particularly to ties of the "class which: =have1-upper transverse ribs intended tOlllOld the foot'ofdthe railin position in "a laterakdirecition. :The invention primarily consistsdn thefactthat the transverse-ribs extend the eritirewvidth of the top surface ot the tie :withoutzany interruption andare integral with the tie,:iandthat each of these ribssinclu d'es a cavity or chamber for-the fas- Htening r-means, vwhichchamber-"is closed 'towar'd the foot-of the rail.

In order that the invention may beclearly 'under st'ood and readily carried into ellect, three embodiments ofthe-same are illustrated by Way of example in-vthe accompanying drawings in which p Figure 1 is a crosssection: of the ant-proved tie-forming'the'first embodiment,

The

bearing surfaces 18, Figure 6, for the outer leg of the clip may lie at the same level as the top surface of the tie or may heat asomewhat lower level, as indicated by a dotted line in Figure 6, left side, whereby the lntroduction of the fixing bolt is'facilitated or its head may be made somewhat higher. If required, strengthening ribs 19 may bev provided on the underside of the top wall 10. of

the tie 9 which'ribs may be produced in the course of rolling the tie. The transverse ribs 11, strengthening ribs 17 as well asthe cavity 13 and recess 16 may be produced by one and the same pressing operation whereby the manufacture of the tie is notably simplified and rendered less expensive.

In the embodiment of the lmproved tie illustrated in Figures 7 to 9, the transverse ribs 20 are produced by pressing'them out of the top material of the tie 32. Each of these ribs 20 has full inner and outer vertical side walls 22 and 23, respectively, without any recess, while in the topwall existing between these two vertical side walls there is provided an oblong or rectangular hole 25,Figure 8,which may be punched out at the same time that the ribs 20 are pressed.- In this embodiment the space existing between the walls 22 and 23 is only so large as to receive the-rectangular head of the fixing bolt 26. The bearing faces of the head 27 of bolt 26 abut on the underside of the top wall of the tie, the bolt 26 being protected from turning by a square portion 28 provided on its shanki As may be seen in Figures 8 and 9, the ribs 20 subside into the top surface of the tie32 bysloping surfaces 29v which extend from their walls 22, and form recesses 30 on the surface of the tie. These recesses receive theouter legs of the clips 31. In applying the bolt 26, its head 27 is introduced in the oblong-hole 25 I and the bolt lowered to such an extent that after turning it 90 the head 27 engages the underside of the wall 24 of the tie."

The top wall 24 of the tie may be rolled throughout with a suitable uniform thickness, or may be thickened only at the bearing places.

- making the ribs 20 and oblong holes 25 may be chosen in such a manner that the material a forced away in the pressing operation serves I to strengthen the adjacent walls so that the oblong holes are flanged. In this way, as

well as by suitably rounding the edges of the-holes, any formation of cracks and the I? like is overcome.
